Detailed Description

Fig. 1 is a schematic diagram of an electrical connection module 10 in a secure electrical connector according to one embodiment of the present invention; FIG. 2 is a rear view of the electrical connection module 10 shown in FIG. 1; FIG. 3 is an exploded view of the components of the electrical connection module 10 shown in FIG. 1; fig. 4 is a schematic cross-sectional view taken along section line a-a of the electrical connection module 10 in fig. 2; fig. 5 is an exploded view of the removable insert compartment of the electrical connection module 10 shown in fig. 1.

The electrical connection module 10 in the safety electrical connector of the present embodiment is used for connecting an external plug, which may be various power plugs, such as a household ac electrical plug. The plug shape may be of various standard forms, such as two-pronged, splayed, two-pronged, three-pronged, etc. In the present embodiment, a two-pin flat plug and a three-pin flat plug meeting the national standard of china are mainly taken as examples for description, and a person skilled in the art can set the electrical connection module 10 matched with plugs of other specifications based on the technical idea of the present embodiment.

The electrical connection module 10 includes: a plurality of plug-in bays 110, a plurality of power connection terminals 120. Each socket 110 is adapted to receive a prong of a plug and is connected to a power connection 120. After all the pins of the plug are inserted in place, the electrical connection module 10 is electrically connected to a power supply and can supply power to the plug.

The plurality of plug-in compartments 110 are spaced apart from each other and arranged in a shape adapted to the pins of the external plug so that the pins of the external plug can be inserted into the plug-in compartments 110 from the tops thereof, the top ends of the plug-in compartments 110 have plug-in compartment openings 111 facing the same direction, and the plug-in compartment openings 111 of the plurality of plug-in compartments 110 have a shape adapted to the pins of the external plug so that the external plug can be inserted into the plug-in compartments 110 from the plug-in compartment openings 111. The shape of the receptacle 110 and the placement of the receptacle openings 111 of the electrical connection module 10 in this embodiment may be designed according to the external plug to be fitted. The prongs of the plug are inserted into the interior of the receptacle 110 through the receptacle openings 111.

The plurality of power connection terminals 120 are disposed in one-to-one correspondence with the plurality of receptacle modules 110, respectively. Each power connection terminal 110 is used for connecting a power line. For example, may include a hot connection, a neutral connection, a ground power connection, etc. Accordingly, the pod 110 may include: a live plug compartment 112 and a neutral plug compartment 113. The electrical connection module 10 of the embodiment shown in fig. 1-5 includes two plug bays 110, which may be a hot plug bay 112 and a neutral plug bay 113, respectively.

At least one of the plurality of plug-in compartments 110 is a movable plug-in compartment, a movable electrical connection end 121 is fixedly connected to the movable plug-in compartment, and moves integrally with the plug-in of the plug-in pin, and the movable electrical connection end 121 is driven by the movable plug-in compartment to approach and finally contact the corresponding power connection end 120, so that the movable plug-in compartment is electrically connected to the corresponding power connection end 120. The whole motion of the movable inserting cabin is driven along with the insertion of the plug. If the type of the plug is not matched with the electric connection module 10, the plug cannot promote the whole movement of the movable plug cabin, and the movable electric connection end cannot be connected with the corresponding power connection end 120, so that the plug pins are ensured to be uncharged. Likewise, if another electrical conductor is inserted into the movable plug compartment by mistake, the electrical conductor cannot make the movable plug compartment move integrally at the same time, so that the electrical connection module 10 can ensure that the electrical conductor cannot be electrically connected to the power connection terminal 120.

The movable electrical connection terminal 121 is disposed outside the movable plug housing in the interior space for the contact pins, for example, the movable electrical connection terminal 121 may be disposed outside the peripheral wall of the housing of the movable plug housing or may extend further outward from the peripheral wall of the housing.

The live plug compartment 112 and the neutral plug compartment 113 may both be movable plug compartments. Accordingly, the power connection 120 includes a line connection 122 that mates with the line receptacle 112 and a neutral connection 123 that corresponds to the neutral receptacle 113. The simultaneous movement of the live and neutral plug compartments 112, 113 is defined by the relative positions of the pins, and the power supply will only be switched on if the adapter pins are inserted simultaneously and connected to the live and neutral connections 122, 123. Neither the hot plug 112 nor the neutral plug 113 has an appropriate pin inserted, and the power is not turned on. I.e. the electrical connection module will only be powered on when a suitable plug is inserted.

The overall movement of the movable bay with the insertion of the pins is a swinging movement about a pivot 131. The swing motion mode is restricted by the rotating shaft, and compared with a translational pushing mode, the swing motion mode is more reliable and has long service life. The rotating shaft 131 may be disposed on a region of the sidewall of the movable inserting compartment near the bottom, that is, an end of the movable inserting compartment far from the opening of the inserting compartment. That is, the movable cabin is provided with a rotating shaft 131 at a position close to the bottom.

The electrical connection module 10 may further include: a restoring member 141. The reset element 141 is used to keep the movable electrical connection end 121 disconnected from the corresponding power connection end 120 in the normal state (state where no plug is inserted) of the movable plug compartment; furthermore, the restoring element 141 provides a certain damping for the movable plug compartment.

The electric connection module 10 of the present embodiment achieves a waterproof function by improving the sealing property. The electrical connection module 10 further comprises: module body 151, waterproof cover plate 152. Wherein the module body 151 defines an installation space for arranging the plurality of plug-in compartments 110, and has a waterproof mating surface 153 exposing the plug-in compartment openings 111 of the plurality of plug-in compartments 110, the waterproof mating surface 153 being provided with a waterproof groove 154 at a position near its own edge. The module body 151 provides a fixed structure for the receptacle 110 and the power connection terminals 120. The module body 151 provides a sheath 155 made of an insulator around the plug-in compartment 110, and the sheath 155 provides a corresponding shaft hole (located inside the module body, not shown) at a corresponding position of the rotation shaft 131 of the movable plug-in compartment to be fitted with the movable plug-in compartment. The module body 151 provides mounting structure for the pod 110 on the one hand and also limits the movement of the pod on the other hand.

The waterproof cover plate 152 is disposed on the waterproof mating surface 153, and a surface thereof facing the waterproof mating surface 153 has a waterproof strip that mates with the waterproof groove 154, and a surface opposite to the waterproof mating surface 153 may be formed as a concave-convex surface 156. The face of the secure electrical connector housing may have a shape that mates with the relief surface 156 at a location opposite the relief surface 156. The waterproof cover plate 152 may be made of a material having a certain reversible deformation, such as resin, rubber, etc., and the waterproof cover plate 152 realizes the overall sealing of the electrical connection module 10 by being tightly crimped with the module main body 151 and the secure electrical connector housing.

Each pod 110 may include: a capsule 130, a pin terminal 132, and a conductive connector 135. The body 130, which is the main body of the pod 110, is made of an insulating material and defines a receiving cavity 137 with a pod opening 111. The pin terminals 132 are disposed in the receiving cavities 137 for connection with the inserted pins. The pin terminals 132 may be shaped to match the shape of the pins, for example, for flat pins, the pin terminals 132 may form a spring clip as shown in fig. 4 and 5. In some embodiments, the pin terminal 132 extends toward the bottom of the housing 130 with a threaded post 133 that engages a nut 134 to secure the pin terminal 132 within the housing 130.

The conductive connector 135 is connected to the pin terminal 132 at the bottom end of the housing 130 (i.e., the end opposite the receptacle opening 111) by a connector and extends outwardly from the housing 130. For a removable pod, the conductive connector 135 may be connected to the removable electrical connector 121. In other embodiments, the movable electrical connection 121 may be integrally formed with the conductive connector 135, with a portion of the conductive connector 135 outside of the interior space (receiving cavity 137) for the contact pin serving as the movable electrical connection 121. The conductive connection member 135 may be specifically shaped to extend from the bottom end of the cabin 130 to the side wall of the cabin 130, and extend from the side wall of the cabin 130 toward the cabin insertion opening 111, and then extend out of the cabin 130 and finally face the power connection terminal 120. That is, the conductive connection 135 extends from the bottom of the receptacle 110 to the side walls of the body 130 and extends outwardly from the side walls. The outer side of the cabin 130 may further have a fixing structure for fixing the conductive connection member 135.

For bays other than the active bay, the conductive connector 135 may be connected to a corresponding power connection. For example, the conductive connection 135 of the ground pod may be directly connected to the ground terminal.

In the embodiment where the pin terminal 132 is engaged with the nut 134 by the screw 133, the conductive connector 135 may also have a screw hole adapted to the screw 133. That is, the conductive connector 135 is connected to the pin terminal 132 from the bottom of the receptacle via the nut 134 (or other connector) without the perimeter wall of the receptacle 130 being perforated.

The outer side of the cabin 130 may further have an outwardly protruding shaft 131, which is engaged with the cabin-inserting opening 111 in the module body 151 to realize the overall swing of the movable cabin.

The peripheral wall of the housing 130 is a continuous wall and defines a receiving cavity 137 having a housing opening 111. Compared with the prior art that the wall surface of the inserting cabin needs to be provided with the hole, the sealing performance is better under the condition that an additional sealing structure is not needed, and the safety is further improved.

The pod 110 may also include guides 136. The guide 136 is disposed in the receiving cavity 137 at a position close to the top, that is, close to the receptacle opening 111, and has a chamfer (or an inclined surface) inclined toward the receiving cavity 137 to guide the insertion of the pins into the interior of the receptacle 110. The guides 136 on the one hand facilitate smooth insertion of the plug and on the other hand also limit the position of the pins within the housing 137.

The embodiment shown in fig. 1-5 is an electrical connection module 10 that mates with a two-pin plug. The plurality of plug compartments include a live plug compartment 112 and a neutral plug compartment 113, and both the live plug compartment 112 and the neutral plug compartment 113 are movable plug compartments. In the electrical connection module 10 of this embodiment, the guides 136 of the hot and neutral plug compartments 112 and 113 may be disposed near the center of the plug compartment 110 and gradually extend obliquely into the plug compartment 110 to guide the pins for smooth connection with the pin terminals 132.

Fig. 6 and 7 are schematic views of the electrical connection module 10 shown in fig. 1 in a power-off state, and fig. 8 and 9 are schematic views of the electrical connection module 10 shown in fig. 1 in a connection state.

The reset member 141 is disposed between the live wire insertion compartment 112 and the neutral wire insertion compartment 113, and includes a first reset portion 143 abutting against the live wire insertion compartment 112 and a second reset portion 144 abutting against the neutral wire insertion compartment 113. The reset element 141 may be configured to provide a reset force that moves the active electrical connection 121 of the line and neutral plug bays 112, 113 away from the respective power connection 120 such that the line and neutral plug bays 112, 113 maintain a disconnected state from the respective power connection 120 when the pins are unplugged. The restoring member 141 may preferably be formed as a single piece, resulting in a simple and reliable structure.

The rotating shafts 131 of the live wire insertion compartment 112 and the neutral wire insertion compartment 113 are arranged in parallel. And the reset rotating shaft 142 is arranged between the live wire inserting cabin 112 and the zero wire inserting cabin 113 and is parallel to the rotating shafts 131 of the live wire inserting cabin 112 and the zero wire inserting cabin 113 respectively. The reset member 141 may be a torsion spring having a central hole penetrating the reset rotary shaft 142, and elastic pieces extending from the central part to the live wire insertion compartment 112 and the neutral wire insertion compartment 113 as a first reset part 143 and a second reset part 144, respectively. The first and second reset portions 143, 144 respectively contact the live and neutral plug bays 112, 113. As the pin is inserted deeper, the restoring member 141 is gradually compressed; i.e., as the insert reset 141 provides a greater reaction force (reset force).

The movable electric connecting end 121 of the live wire plug cabin 112 is arranged on one side opposite to the zero wire plug cabin 113 and extends outwards along the side wall of the live wire plug cabin 112 where the live wire plug cabin is located; the movable electric connecting end 121 of the zero line plug cabin 113 is arranged on one side opposite to the live line plug cabin 112 and extends outwards along the side wall of the zero line plug cabin 113 where the movable electric connecting end is arranged; and the extending direction of the movable electrical connection end 121 of the live wire plug compartment 112 is opposite to the extending direction of the movable electrical connection end 121 of the zero wire plug compartment 113; the power connection end 120 comprises a live wire connection end 122 corresponding to the live wire plug-in compartment 112 and a neutral wire connection end 123 corresponding to the neutral wire plug-in compartment 113, the live wire connection end 122 is arranged on one side, extending out of the movable electric connection end 121 of the live wire plug-in compartment 112, and the neutral wire connection end 123 is arranged on one side, extending out of the movable electric connection end 121 of the neutral wire plug-in compartment 113.

In the angles shown in fig. 6 and 8, the live wire insertion compartment 112, the rotating shaft 131 of the neutral wire insertion compartment 113 and the reset rotating shaft 142 are all vertically arranged in parallel, the live wire insertion compartment 112 is located on the right side, the neutral wire insertion compartment 113 is located on the left side, the conductive connecting piece 135 of the live wire insertion compartment 112 extends from the bottom of the live wire insertion compartment 112 to the right side wall and then extends downwards, and the extending part is the movable electrical connection end 121; and the zero line plug cabin 113 is positioned at the left side, the conductive connecting piece 135 of the zero line plug cabin 113 extends from the bottom of the live line plug cabin 112 to the left side wall and then upwards, and the extending part is the movable electric connecting end 121. The live connection end 122 extends from below towards the live insertion compartment 112 and is opposite at its end to the active electrical connection end 121 of the live insertion compartment 112, and the neutral connection end 123 extends from above towards the live insertion compartment 112 and is opposite at its end to the active electrical connection end 121 of the neutral insertion compartment 113.

In a normal state, the live wire insertion compartment 112 and the neutral wire insertion compartment 113 are integrally in an inverted V shape from top to bottom, that is, the live wire insertion compartment 112 and the neutral wire insertion compartment 113 are respectively inclined towards the center. As the plug is advanced further, the pins overcome the reset force of the reset member 141, causing the respective live and neutral compartments 112, 113 to swing towards the center. That is, the live and neutral plug bays 112 and 113 converge inwardly. Finally, due to the limit of the pins of the plug, the live wire insertion compartment 112 and the neutral wire insertion compartment 113 are arranged in parallel, and the movable electric connecting end 121 of the live wire insertion compartment 112 and the movable electric connecting end 121 of the neutral wire are in contact with the live wire connecting end 122 and the neutral wire connecting end 123. When any conductive object other than the adaptive plug is inserted, the applied force is reacted by the inverted-V structure, and the larger the applied force is, the larger the clamping force is, and the movable plug compartment cannot be simultaneously electrically connected to the power connection terminal 120.

The live connection end 122 and the movable electrical connection end 121 of the live socket 112 may have live contacts 138 oppositely arranged and are connected through the live contacts 138; neutral connection 123 has a neutral contact 139 disposed opposite the movable electrical connection 121 of neutral plug bay 113 and is connected via neutral contact 139. The contact reliability can be ensured by utilizing the contact connection.

Neither the live wire plug compartment 112 nor the neutral wire plug compartment 113 is plugged in place, or the plugging plugs are not matched, so that the power supply is not conducted. The electric conductors are inserted into any inserting cabin independently, and the electric conductors cannot conduct electricity unless the appearance structure is damaged, so that electric shock accidents are avoided.

The present embodiment also provides an electrical connection module 20 that fits a three-pin plug. Fig. 10 is a schematic view of another electrical connection module 20 in a safety electrical connector according to an embodiment of the present invention; FIG. 11 is a rear view of the electrical connection module 20 shown in FIG. 10; fig. 12 is an exploded view of the components of the electrical connection module 20 shown in fig. 10. The electrical connection module 20 of this embodiment is used for connecting a three-pin plug, wherein the plug compartment may further include a ground plug compartment 114 in addition to the live plug compartment 112 and the neutral plug compartment 113, the ground plug compartment 114 is arranged in a triangular shape with the live plug compartment 112 and the neutral plug compartment 113, and the reset piece 141 is disposed in an area surrounded by the ground plug compartment 114, the live plug compartment 112, and the neutral plug compartment 113, and has elastic pieces extending toward the live plug compartment 112 and the neutral plug compartment 113, respectively, and the elastic pieces serve as a first reset portion 143 and a second reset portion 144, respectively. The first and second restoring portions 143 and 144 may be U-shaped spring plate structures, respectively. The ground plug compartment 114 may be fixedly disposed.

The live plug compartment 112 and the neutral plug compartment 113 in this embodiment are both movable plug compartments, and the structures of the live plug compartment 112 and the neutral plug compartment 113 are the same as those of the previous embodiment or the movable plug compartments, and only the differences exist in the layout and relative positions with respect to the electrical connection module 10. The bay itself may also include: a capsule 130, a pin terminal 132, and a conductive connector 135. The extension lines of the rotating shafts 131 of the live wire insertion compartment 112 and the neutral wire insertion compartment 113 are at a certain angle, for example, 60 degrees. The reset element 141 may be secured by connectors to the central area enclosed by the ground receptacle 114, the line receptacle 112, and the neutral receptacle 113.

Fig. 13 is a schematic view of the electrical connection module 20 shown in fig. 10 in a power-off state, while fig. 14 is a schematic view of the electrical connection module 20 shown in fig. 10 in a connected state.

The movable electrical connection end 121 of the live wire plug 112 may be disposed on a side opposite to the neutral wire plug 113, and extend outward along a side wall of the live wire plug 112 where the live wire plug is located; the movable electrical connection end 121 of the neutral plug 113 may be disposed on a side opposite the live plug 112 and extend outwardly along a side wall of the neutral plug 113 on which it is disposed. That is, the movable electrical connection end 135 of the live plug compartment 112 and the movable electrical connection end 135 of the neutral plug compartment 113 are located on the outward side of the live plug compartment 112 and the neutral plug compartment 113, respectively.

In addition, the extending direction of the movable electric connecting end 121 of the live wire inserting chamber 112 is opposite to the extending direction of the movable electric connecting end 121 of the zero wire inserting chamber 113; at the angle shown in fig. 13 and 14, the active electrical connection 121 of the live plug bay 112 extends obliquely downward, while the active electrical connection 121 of the neutral plug bay 113 extends obliquely upward. In the normal state, the live plug 112 and the neutral plug 113 are inclined from top to bottom toward the center as a whole. As the plug is progressively advanced, the prongs overcome the reset force of the reset member 141, causing the respective live and neutral compartments 112, 113 to swing inwardly. That is, the live and neutral plug compartments 112, 113 converge inwardly. Finally, due to the limit of the pins of the plug, the movable electrical connection end 121 of the live wire insertion compartment 112 and the movable electrical connection end 121 of the neutral wire insertion compartment 113 are in contact with the live wire connection end 122 and the neutral wire connection end 123, so that electrical connection is realized. If any one of the live wire plug cabin 112 and the zero wire plug cabin 113 is not plugged in place, or the plugging joints do not correspond, or other electric conductors are inserted into the movable plug cabin by mistake, the movable plug cabin can be ensured not to be simultaneously electrically connected to the corresponding power supply connecting ends 120, and the power supply can not be conducted. The electric conductor is inserted into any inserting cabin independently, and the electric conductor cannot conduct electricity, so that electric shock accidents are avoided.
